Almont WWTP Improvements

The Village of Almont’s wastewater treatment plant is an activated sludge plant with a process of screening and grit removal, secondary treatment using extended aeration, final clarification, tertiary treatment using sand filters, and UV disinfection, followed by discharge to the north branch of the Clinton River. While much of the mechanical equipment within the plant’s system was in good working order, other portions had reached the end of their useful life and needed replacement.

Rotor brush blades, splash plates, and level control effluent weir plates were replaced on the horizontal bladed rotor aerators in the plant’s oxidation ditches, and concrete coating was added to areas of the tank walls. In each of the plant’s two 30-foot diameter clarifiers, mechanical parts of the clarifiers were replaced, including the scraper arm assemblies, shafts, effluent weirs/troughs, influent troughs, and scum valves. To combat algae growth and insects in the clarifiers, dome covers were installed.

Spicer Group provided professional engineering services to prepare design drawings, bidding documents, assist with the bidding phase of the project, and construction administration and inspection phase on this project.
